Slippage is determined by monitoring the shaft speed into the clutch as well as the shaft speed ... 01/25/07 - 20070021268 - Method and apparatus for estimating transmission ratio A method and apparatus for estimating a transmission ratio of a power transmission path defined between input and output shafts is provided. The method includes detecting a rotational speeds of the input and output shafts, calculating a rotational-speed ratio between the detected rotational speeds of the input and output shafts, ... 01/04/07 - 20070004555 - Engine shut-down control to reduce or eliminate engine run-on A vehicle powertrain including a multiple cylinder internal combustion engine and a controllable transmission controls engine shutdown by shutting off a fuel supply device or devices such as a fuel pump or fuel injector(s) while the transmission is in gear to load the engine and reduce or eliminate engine run-on. ... 12/14/06 - 20060281601 - Control device for vehicle A cruise control device executes a program including the steps of: when shift information transmitted from an ECT-ECU changes from fifth gear to fourth gear, and the time T (1) from a change in the shift information has elapsed, determining that down shifting to fourth gear has been conducted, effecting ... 11/23/06 - 20060264298 - Engine torque error learn during dynamic vehicle test A method of regulating gear shifts of a transmission driven by an engine includes calculating a first torque error and calculating a second torque error. A compensation torque is determined based on the first torque error and the second torque error. The gear shifts are regulated based on the compensation ... 06/15/06 - 20060128525 - Gear change control device and method A gear change control device is provided for a straddle-type vehicle having a clutch and a transmission. The device includes a clutch actuator configured to engage and disengage the clutch. A transmission actuator is configured to change a gear of the transmission. At least one sensor is configured to sense ... 06/01/06 - 20060116239 - Mechanical automatic transmission apparatus During a period in which a clutch is in a partially engaged state at the time of start of a vehicle, a transmission ECU calculates load acting on the clutch (clutch-absorbed energy). When this load is large, generation of a shift signal based on a gear shift map is prohibited, ... 04/27/06 - 20060089236 - Transmission control based on knock level An automated method for controlling a vehicle having an engine and a transmission includes sensing knock activity in the engine. A transmission ratio applicable to the transmission is selected based on the sensed knock activity. This method allows a vehicle to be operated in a fuel-efficient manner while knock-sensitive operating ... 04/13/06 - 20060079375 - Hydraulic regenerative drive system and controls A hydraulic regenerative drive system for a vehicle is disclosed. An electronic controller (28) receives a nominal engine throttle signal (35) and generates a time-variant torque signal (26) therefrom. A hydraulic control circuit (18) receives controlling signals (15) from the electronic controller (14). A reservoir (62) is in fluid communication ... 03/09/06 - 20060052217 - Process and device for preventing the engagement of an impermissible speed in an automated gearbox A process for preventing the engagement of an impermissible speed in an automated gearbox with a gear-switching member, which can be moved along a gear-selection speed range and out of it into speed step ranges containing the following steps: acquiring the speed step range in which the gear-switching member is ... 02/16/06 - 20060035749 - Ratio selection method for a continuously variable transmission A gear ratio selection method for a transmission in a motor vehicle includes detecting a power request, detecting a vehicle speed of the motor vehicle, and providing an engine speed of the motor vehicle. A first desired engine speed is calculated from a first variogram using the power request and ... 12/08/05 - 20050272557 - Traveling gear for agricultural working machine A traveling gear for an agricultural working machine, with control of he traveling speed by adjusting the engine sped to the planned driving for road travel is disclosed. The traveling gear for an agricultural working machine controls the speed for road travel by controlling the central drving gear. ... 10/06/05 - 20050221952 - Engine starting system An engine starting system includes a throttle valve, an alternator, an engine speed sensor and an electronic control unit (ECU). The ECU functionally includes an automatic engine stop controller for automatically stopping the engine by interrupting fuel injection when predefined automatic engine stop conditions are satisfied, and an automatic engine ... 10/06/05 - 20050221951 - Method for triggering the clutch moment of a clutch of an automated gear and device for implemention of the method A method is proposed for triggering the clutch moment of a clutch of an automated gear in the power train of a vehicle with the creep function activated, where the clutch moment is triggered as a function of the slippage on the clutch and/or as a function of the speed ... 09/22/05 - 20050209046 - Control of transmission shift points for hybrid vehicle having primary and secondary power sources A method, used in a powertrain of a motor vehicle having an engine, a secondary power source, and a step-change automatic transmission for driving a load, controls an upshift from a current gear to a next gear and includes the steps of establishing first shift points of a demanded engine ... 08/11/05 - 20050176555 - Operating position select device for automatic transmission An operating position select device has a select lever unit, a mode shift unit to shift operation modes of the automatic transmission, a mechanically connecting means connecting them, and an assist actuator to apply assist force to a select lever of the select lever unit.
